An inhabitant of the trunks of trees in swampy, low 
situations, in the æstuaries Of the rivers of Bengal and 
Pegu, according to Dr. Wallich, to whom the Gardens of 
England are indebted for the introduction of this curious 
species. In its natural position it is pendulous; but in our 
drawing it is represented erect,—the plant in the Garden 
of the Horticultural Society from which the figure was 
taken, having at that time been tied to a stake. It flowers 
at uncertain seasons, and grows more freely than other 
plants with a similar habit. 
In appearance it is very like the Herba supplex quinta 
of Rumphius, vol. 6. p. 111. t. 51. f. 2; but that plant has 
spiked flowers, and, Dr. Wallich informs us, is quoted by 
Roxburgh in his MSS. to his Dendrobium acinaciforme. 
* From dido», a tree, and 4%, life. All the genuine species are found 
upon trees, in the hot parts of the East Indies.
